Aliyah and Diego started to run in a 5 kilometer-long race at exactly the same time. By 3:00 P. M., Aliyah had completed half of the race. For the rest of the race, Aliyah ran at a constant rate of 0.25 kilometer per minute. Diego did not run the race at a constant speed. A linear function can be used to model the total distance d(t)d(t) , in kilometers, that Aliyah runs from the beginning of the race in t minutes, where t=0t=0 represents 3:00 P. M. Write an equation that defines the linear function d. Explain how you determined the equation for the function.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

hope to and hope that my answer is brainliest.(follow me )

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
